4 Claims. (01. 237-12.3)

This invention relates to the'provision' of an of the water circulating space of the engine 5. improved system for regulating the temperature, By this arrangement, water heated by the opand otherwise conditioning, the atmosphere eration of the engine 5 will be 'allowed'to cirthe passenger compartment or a motor vehicle. culate through the temperature regulator to heat 5 A primary object 01' the invention resides in the air contacted with the parallel tubes of the 5 provision of automatic means for controlling the regulator. I introduction of fresh air into a vehicle body and The cowl or hood I0 is provided with a venat the same time regulating the temperature of tilating opening l5, which is opened or closed the air to render it suitable for enhancing the by means of a hinged cover member l6.

fiuenced by the temperature of the walls of the What is claimed is:

radiator tubes. When it is desired to employ 1. An automobile heater comprising a radiator the regulator as a heater, the latter is connected mounted adjacent to the passenger compartby means of a flexible tube I3 with the connecment of a vehicle, means for circulating a heated tion 8 of the water circulating system, and by fluid through said radiator, an adjustable closure a corresponding tube H with the upper portion carried in conjunction with the body of the ve- 55 hicle for regulating the passage of air through an opening provided in the vehicle body contiguous to said radiator, and thermostatic means governed by the temperature 01 said radiator and the air passed through said radiator i'or progressively opening or closing the closure respectively in accordance with increase or decrease of said temperature.

2. Temperature regulating apparatus for the passenger compartments of motor vehicles comprising a radiator mounted in connection with the bulkhead of a motor vehicle body behind the instrument panel thereof and immediately beneath a ventilating opening formed in the cowl construction of the vehicle body, an adjustable closure for said ventilating opening, and thermostatic means responsive to the temperature of the radiator and the temperature oi! the air heated thereby for automatically opening and closing said closure progressively in accordance with increase or decreaseo! said temperature.

3. In apparatus for heating the passenger compartment 01 a motor driven vehicle, in combination, a vehicle cowl having a ventilating opening formed therein, a movable closure for governing the passage 01' air through said opening and into the interior of the associated vehicle body, a heater mounted within said cowl in registration with said opening, and thermostatic means governed by the temperature of said heater for automatically varying the degree of opening or said closure, whereby to progressively increase the amount 01 air passing through said opening as the temperature of said heater increases and to progressively decrease theamount of air passing through said opening-asthe perature of the heater decreases,

4. Temperature regulating apparatus ior the passenger compartment of a motor vehicle comprising a radiator mounted adjacent to said compartment, said compartment being provided with a ventilating opening in registration with said radiator, a movable closure for said ventilating opening, a thermostat positioned adjacent said radiator and contacted by air passing therethrough, and a link connecting said thermostat and said movable closure whereby the latter will open or close according to the temperature variation of the radiator.
